2. Oblique Imagery Accuracy and Production
The oblique imagery accuracy will be a horizontal RMSE of 2-pixel and vertical of 3-pixels.
At for oblique imagery systems employs similar techniques of conventional AT; for
example both include the use of ABGPS/IMU data and ground control points. However,
conventional AT software was not designed to incorporate oblique imagery for tie point
18 of 27 Agreement between County of Santa Clara and City of Cupertino – Imagery and LiDAR Project
generation or to handle the large amount of data collected with the system. There are
two approaches Sanborn considers to ensure the highest accuracy possible for the nadir
and oblique imagery:
Perform AT with the nadir image only and, using the results, compute the
orientation of the oblique imagery thus assuring a singular orientation system; or,
Perform point matching on all nadir and oblique frames and utilize additional
parameters; e.g. trajectory and timing information into a bundle block solution.
This approach allows the identification and removal of errors associated with the
individual cameras within the system and with the GPS trajectory. This method
allows for tight quality control through all steps in the process, maximizing the
resultant accuracy of all images in the block.
With both solutions, AGPS/IMU and ground control are key elements in assessing the
final accuracy of the imagery.
Following completion of the data acquisition flight, a suite of image processing, GPS and
inertial data processing, and quality control software is used to produce a set of five
georeferenced images at each exposure station. The image database will be color
balanced, and quality control inspections with be performed to ensure integrity of the
data set.
The completed oblique and nadir images will be uploaded into the Sanborn Oblique
Analyst®.

The angle which is inherent to oblique imagery allows viewers to see not only the top of
objects but the sides as well. All 5 views (1 nadir view and 4 views angled at 45 degrees
from the nadir) are viewable in the Oblique Analyst®. The user can select a view to be the
primary view and then switch back and forth with other views. An overview map is also
available in the bottom right corner of the Oblique Analyst®.
The Oblique Analyst® has a large selection of tools and options to be used while exploring
the imagery. These features include:
The ability to pan and zoom around in the project area to explore views of
the selected location. Users can zoom in and out with the zoom buttons or
use the scroll wheel on the mouse.
A compass feature so users always know the direction of the current
view. The half circle button in the middle indicates the nadir or top-down view.
The triangle button in the center indicates a top-down, north-up navigation view
which is also used to view WMS/WFS layers.
An overview map (bottom right corner) so users know the exact location
within the project area.
An addressing feature to quickly locate a specific address,
incorporating County’s geocoding services.
The Oblique Analyst® allows integration with other software environments through URL
parameters, i.e., users/other applications can start the viewer at a specified location by
using one of the following URL parameters.
Coordinates: http://<Viewer site>/<Viewer name>/?ll=lat,long

as part of the LiDAR production process. This will include the following:
Validating correct file formats and versions;
Reviewing all associated metadata records;
Reviewing 2D footprints and 3D buildings;
Reviewing all calibration and analytical reports produced by Sanborn.
Sanborn provides an optional service for web-based quality checking of lidar data
available to the County. Data is served from a central data server at Sanborn to the
customer-side computer, and uses a mapping interface from within a standard web
browser.
The Sanborn Lidar Web-Viewer™ serves point cloud data through a user-friendly, web-
based interface from a secure cloud environment and delivers the following benefits:
Provides ease and standard documentation for data quality review needed for
contract monitoring and compliance
Facilitates coordination between many data reviewers, even when geographically
separated
Instant access to online point cloud data for review by Sanborn Lidar clients
Accelerated QA/QC review, as clients can flag potential issues for Sanborn
technicians to immediately review and resolve
Secure project management, including role-based access to the data
25 of 27 Agreement between County of Santa Clara and City of Cupertino – Imagery and LiDAR Project
Streamlined processing and standardized documentation, which is invaluable for
contract monitoring and compliance
Faster data delivery times for clients, as the need for hardcopy shipping can be
reduced or eliminated
Reduced client-side IT involvement, as Sanborn can manage the cloud
environment
Users can also view the classified point cloud by classification, elevation, RGB and
intensity value. End users can integrate with vector layers (point, polyline or polygon
shapefiles/geodatabases), including Open Geospatial Consortium (OGC) web-services
such as WMS, WMTS and WFS that can be hosted by the County outside the application.
